You can use FindByName of the root control, or go through the visual tree with this function

public static FrameworkElement FindByName(string name, FrameworkElement root)
{
    Stack<FrameworkElement> tree = new Stack<FrameworkElement>();
    tree.Push(root);

    while (tree.Count > 0)
    {
        FrameworkElement current = tree.Pop();
        if (current.Name == name)
            return current;

        int count = VisualTreeHelper.GetChildrenCount(current);
        for (int i = 0; i < count; ++i)
        {
            DependencyObject child = VisualTreeHelper.GetChild(current, i);
            if (child is FrameworkElement)
                tree.Push((FrameworkElement)child);
        }
    }

    return null;
}

You can also have a look at ItemContainerGenerator. You can probably use ContainerFromIndex or ContainerFromItem methods to get the container of each element.

First you need to call ItemsControl.ContainerFromElement to get the "root-control" for each data item displayed. And the you can use the VisualTreeHelper to iterate over the controls.
